Problems solved by technology

However, in some cases, such as when using a PDA with GPS positioning program in a car, due to the influence of external light, it is often found that the picture of the PDA liquid crystal display is too dark when used during the day, and it is not convenient for the driver to view the display displayed on the display. However, it is too bright when used at night. The strong light will affect the driver's eyes, which may endanger the driving safety. Therefore, it is often necessary to adjust the brightness of the display while driving, which will also distract the driving. The driver's attention is affected, driving safety is affected, and the operation is inconvenient

Embodiment Construction

[0014] The following will take a PDA with GPS as an example to illustrate the method for automatically adjusting the display brightness of the present invention.

[0015] like figure 1 As shown, the device used in the present invention includes a storage module 10 , a time generator 20 and a processing unit 30 . Wherein, the storage module 10 is used to store the brightness setting value corresponding to the time, and the time generator 20 is used to generate the time as the basis for the execution of the processing unit 30 .

[0016] The following will combine figure 2 The method of the present invention is described in detail, wherein related hardware parts please combine figure 1 .

[0017] First store the brightness setting value corresponding to the time in the storage module 10 (step 100);

[0018] The processing unit 30 will detect an activation signal. In this embodiment, the activation signal is the start of operation of the satellite positioning operating system...

Abstract

A method of automatic adjusts the brightness of display according to the time which produces by the time producer. It is: save the corresponding brightness initialization of the time in the storage module, take out the set value from the storage module when the processing unit receives the time from the time producer, adjust the brightness with the set value if the value in the time set range, otherwise, continue to take out other set value until it corresponds. Thus, the brightness of the display change automatically by the different time, which the user can watch the content on the display.

Description

technical field [0001] The invention relates to a method for adjusting the brightness of a display, in particular to a method for adjusting the brightness of a display according to the time generated by an internal time generator of an electronic device. Background technique [0002] Due to the different default settings of the monitors at the factory, users in different situations often need to adjust the image, color or brightness settings of the monitors to achieve a more ideal display environment. [0003] According to the different types of adjustment circuits, the display control methods can be divided into two types: analog control and digital control. Analog control generally adjusts the display mode through the knob provided by the monitor. There are only the most common adjustment functions, which are mainly used in early monitors. The digital control basically adopts micro-touch buttons or single-button shuttle design, which is easy and convenient to operate. Th...
